본발명은 열대야 관수용 양액공급시스템에 관한 것으로, 원수탱크(10)와, 상기 원수탱크(10)의 원수 및 다수 개의 양액탱크(20)에서 양액이 공급되어 혼합되는 믹싱탱크(30)와, 상기 믹싱탱크(30)에서 혼합된 양액이 관수관을 통하여 관수되는 다수 개의 관수용 전자밸브(40)로 이루어지는 열대야 관수용 양액공급시스템에 있어서,The present invention relates to a nutrient solution supply system for a tropical water pipe, comprising a raw water tank (10), a mixing tank (30) in which nutrient solution is supplied and mixed in raw water and a plurality of nutrient tanks (20) And a plurality of pipe-receiving solenoid valves (40) for mixing the nutrient solution mixed in the mixing tank (30) through a water pipe, the system comprising:

상기 원수탱크(10)의 원수는 지하관정으로부터 원수흡입펌프와 여과기를 거쳐 원수탱크(10) 내부로 인입된 후, 급수펌프(54)를 통과하여 믹싱탱크(30) 내부로 인입되며, 관수펌프(60)의 관수작용에 의해 관수관에서 분기된 분기관수관과 믹싱탱크(30) 사이에 연결된 각각의 벤츄리(94) 내부에는 음압이 발생하고, 상기 음압에 의해 양액탱크(20) 내부의 양액이 믹싱탱크(30) 내부로 원활하게 흡입되는 것이며, The raw water in the raw water tank 10 is drawn into the raw water tank 10 from the underground water tank through the raw water suction pump and the filter and then flows into the mixing tank 30 through the feed water pump 54, Negative pressure is generated in each of the venturi 94 connected between the branch pipe and the mixing tank 30 branched from the water pipe due to the irrigation of the nutrient solution tank 60 and the nutrient solution in the nutrient solution tank 20 Is smoothly sucked into the mixing tank (30)

과실나무 주위환경이 열대야일때 제어반의 신호에 의해 믹싱탱크에서 혼합된 양액이 과실나무에 공급되는 것을 특징으로 한다. The nutrient solution mixed in the mixing tank is supplied to the fruit tree by the signal of the control panel when the circumference of the fruit tree is in a tropical zone.

또한, 상기 열대야는 일일최고기온이 30℃이상이고, 또한 밤동안에도 최저기온이 25℃이상인 것을 특징으로 한다.In addition, the tropical night is characterized in that the maximum daily temperature is not less than 30 ° C, and the minimum temperature is not less than 25 ° C during the night.

곧, 상기 믹싱탱크(30)와 관수펌프(60)에 의한 관수방법을 사용하는 것으로, 온도센서에서 감지한 온도가 열대야조건인 일일최고기온이 30℃이상이고 밤동안에도 최저기온이 25℃이상인 경우 관수펌프(60)가 작동하여 전자밸브(40)를 통하여 믹싱탱크에서 혼합된 양액이 과실나무에 공급되는 것을 특징으로 한다.By using the irrigation method using the mixing tank 30 and the irrigation pump 60, it is possible to prevent the temperature sensed by the temperature sensor from exceeding the maximum daily temperature of 30 ° C The irrigation pump 60 is operated so that the nutrient solution mixed in the mixing tank through the solenoid valve 40 is supplied to the fruit tree.

또한, 상기 양액탱크(20)의 양액선택이 제어반에서 바뀔 때 이전양액이 믹싱탱크에 남아 있지 못하도록 양액탱크(20) 선택이 바뀌기 전에 해당 양액탱크(20)는 별도로 설치된 드레인관을 통하여 비워주는 것을 특징으로 한다.
Also, when the selection of nutrient solution in the nutrient solution tank 20 is changed in the control panel, the nutrient solution tank 20 is emptied through a separately installed drain pipe before the selection of the nutrient solution tank 20 is changed so that the previous nutrient solution can not remain in the mixing tank .

본발명을 첨부도면에 의해 상세히 설명하면 다음과 같다. 도 1은 본발명 벤추리관이 설치된 양액시스템 구성도, 도 2는 본발명 벤추리관이 설치된 양액시스템에서 양액공급헤드가 설치된 구성도이다.
The present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram of a nutrient solution system in which a venturi tube of the present invention is installed, and FIG. 2 is a block diagram of a nutrient solution system in which a venturi tube of the present invention is installed.

원수흡입펌프는 자동수위조절기가 설치된 관용의 자동펌프를 사용함으로써, 원수탱크 내부의 원수가 일정수위 이하이면 자동으로 펌프가 작동하며, 일정수위에 도달하면 펌프가 정지하여, 원수탱크를 항상 일정한 수위를 유지하게 한다.
The raw water suction pump uses an automatic pump with an automatic water level controller so that when the raw water inside the raw water tank is below a certain level, the pump automatically operates. When the water level reaches a certain level, the pump is stopped, .

믹싱탱크는 벤츄리를 통과하여 인입된 양액들을 서로 섞어주는 탱크로서 그 용량은 150리터 정도이다.The mixing tank is a tank that mixes the incoming nutrients through the venturi and has a capacity of about 150 liters.

그리고 상기 양액공급과 관수를 제어하는 제어반이 함께 설치된다.And a control panel for controlling the nutrient solution supply and the irrigation water are installed together.

본발명 양액공급시스템의 최대 관수 능력은 약12,000 ~ 34,000리터 / 시간이며, 양액공급은 10 ~ 500리터 / 시간이다. 그리고 본발명의 액비 제어는 양액 설정치에 의한 비례제어를 한다.The maximum irrigation capacity of the present invention nutrient supply system is about 12,000 to 34,000 liters / hour, and the nutrient supply is 10 to 500 liters / hour. The liquid control of the present invention performs proportional control by the nutrient solution setting value.

본발명의 기계중량은 약80Kg이 되며, 전원은 삼상 4선식 AC380V/60Hz 또는 단상 AC220V/60Hz를 사용한다.The machine weight of the present invention is about 80 Kg, and the power source uses three-phase four-wire type AC380V / 60Hz or single-phase AC220V / 60Hz.

본발명은 액비를 위한 양액을 장소와 시간에 따라 혼합량을 달리하여 그룹별로 차별적으로 관수할 수 있는 것으로, 여러 개의 양액탱크에서 전부 또는 일부만을 선정하여 믹싱탱크에서 혼합하며, 관수대상도 전부 또는 일부만을 선정하여 각기 그에 맞는 그룹을 정하며 시간대를 같거나 달리하여 관수하는 것이다.
In the present invention, the nutrient solution for liquid fertilizer can be irrigated differently in different groups depending on the place and time, and all or part of the nutrient tanks are selected and mixed in a mixing tank. And select the appropriate group for each of them.

본발명 벤츄리가 설치된 양액공급시스템은 원수탱크와, 상기 원수탱크(10)의 원수 및 다수 개의 양액탱크(20)에서 양액이 공급되어 혼합되는 믹싱탱크(30)와, 상기 믹싱탱크(30)에서 혼합된 양액이 관수관을 통하여 관수되는 다수 개의 관수용 전자밸브(40)로 이루어진다.The nutrient solution supply system provided with the venturi of the present invention comprises a raw water tank, a mixing tank 30 in which nutrient solution is supplied and mixed in the raw water and a plurality of nutrient tanks 20 of the raw water tank 10, And a plurality of pipe-receiving solenoid valves 40, through which the mixed nutrient solution is irrigated through the irrigation pipes.

상기 원수탱크(10)의 원수는 지하관정 또는 지표면으로부터 관용적으로 널리 사용되는 원수흡입펌프와 여과기를 거쳐 원수탱크(10) 내부로 인입된 후, 급수펌프(54)를 통과하여 믹싱탱크(30) 내부로 인입된다.The raw water in the raw water tank 10 is drawn into the raw water tank 10 through a raw water suction pump and a filter which are widely used from the underground tank or the earth surface and then flows into the mixing tank 30 through the feed pump 54, .

그리고 양액공급에 대해 기재하면, 관수펌프(60)의 관수작용에 의해 관수관과 믹싱탱크 사이에 연결된 각각의 벤츄리(94) 내부에는 음압이 발생하고, 상기 음압에 의해 양액탱크(20) 내부의 양액이 믹싱탱크(30) 내부로 원활하게 흡입되는 것이다. In this case, negative pressure is generated in each venturi 94 connected between the water supply pipe and the mixing tank by the irrigation action of the irrigation pump 60, The nutrient solution is sucked into the mixing tank 30 smoothly.

상기 다수 개의 양액탱크(20)의 양액은 개폐밸브(92), 벤츄리(94)를 순차적으로 통과한 후 믹싱탱크(30) 내부로 인입된다.The nutrient solution of the nutrient solution tank 20 is sequentially introduced into the mixing tank 30 after passing through the opening and closing valve 92 and the venturi 94 in sequence.

그리고 상기 믹싱탱크(30) 내부의 혼합된 양액은 관수펌프(60)를 거쳐서 다수개의 전자밸브(40)를 통해 관수된다.The mixed nutrient solution in the mixing tank 30 is fed through a plurality of solenoid valves 40 via a water pump 60.

한편 상기 벤츄리 각각에는 개폐밸브(92)가 설치되고, 또한 각각의 벤츄리는 하나의 양액공급헤드에 연결되며, 상기 양액공급헤드는 믹싱탱크에 연결되는 것이다. 그러므로 상기 각각의 벤츄리를 통해 공급된 양액들은 양액공급헤드에서 균일하게 먼저 혼합된 뒤 믹싱탱크에 공급되는 것이다. 그리고 상기 벤츄리는 관용적으로 실험실이나, 유체기계분야에서 널리 사용되는 것을 사용하면 되는 것이므로, 자세한 설명은 생략한다.On the other hand, each of the venturi is provided with an opening / closing valve 92, and each venturi is connected to one nutrient solution supply head, and the nutrient solution supply head is connected to the mixing tank. Therefore, the nutrient solutions supplied through the respective venturi are uniformly mixed first in the nutrient solution feed head and then supplied to the mixing tank. Since the venturi can be used in a laboratory or a fluid machine widely, it will not be described in detail.

또한, 본발명은 상기 급수펌프가(54)가 관수펌프(60)보다 일정 시간, 통상 3초 정도 빨리 작동시킨다. 그러므로 펌프 급수펌프와 관수펌프가 동시작동을 할 때 생기는 높은 기동전력을 분산시킴으로서 안정적인 전력공급을 할 수 있게 된다.Further, in the present invention, the feed pump 54 operates for a certain time, usually about 3 seconds, more than the irrigation pump 60. Therefore, stable power supply can be achieved by dispersing the high starting power generated when the pump water supply pump and the water supply pump operate simultaneously.

또한, 본발명은 양액탱크의 양액을 제어반에서 새로운 것으로 바꿀 때, 이전양액이 믹싱탱크에 남아 있지 못하도록 양액탱크 선택이 바뀌기 전에 해당 양액탱크는 별도로 양액탱크 하부에 설치되는 드레인관을 통하여 비워주게 된다. 곧 상기 드레인관에는 전자밸브가 설치되어 있어서, 제어반에서 새로운 양액을 선택하는 것으로 결정되면, 제어반에서 전기신호를 전자밸브에 보내게 되어 전자밸브를 열게 되어 내부의 잔존 양액을 드레인시킨다. 그리고 전자밸브를 닫게 되며, 이후 새로운 양액이 공급된다. In addition, when the nutrient solution in the nutrient solution tank is changed to a new one in the control panel, the nutrient solution tank is emptied through a drain pipe separately provided under the nutrient solution tank before the selection of the nutrient solution tank is changed so that the previous nutrient solution does not remain in the mixing tank . The drain pipe is provided with a solenoid valve. When it is determined that the control panel selects a new nutrient solution, the control panel sends an electric signal to the solenoid valve to open the solenoid valve to drain the remaining nutrient solution. Then, the solenoid valve is closed, and then a new nutrient solution is supplied.

한편, 전기전도도를 측정하는 EC 센서와 산성,알칼리성을 측정하는 PH센서는 관용적으로 널리 사용되는 것을 사용하는 것으로, 설치위치는 EC 센서는 믹싱탱크와 관수펌프 사이에 설치하고, PH센서는 벤츄리 후단과 믹싱탱크사이에 설치한다.On the other hand, the EC sensor for measuring the electric conductivity and the PH sensor for measuring the acidity and the alkalinity are widely used, and the EC sensor is installed between the mixing tank and the irrigation pump, And the mixing tank.

한편, 본발명은 기존의 믹싱탱크와 관수펌프에 의한 관수방법을 사용하되, 온도센서에서 감지한 온도가 상기 열대야조건인 일일최고기온이 30℃이상이고 밤동안에도 최저기온이 25℃이상인 경우에는 다른 관수 제어조건에도 불구하고 관수펌프가 작동하여 전자밸브(40)를 통하여 일정시간 관수되게 된다. 관수계속시간은 제어반에서 설정할 수 있다.Meanwhile, in the present invention, when the temperature sensed by the temperature sensor is higher than the maximum daily temperature of 30 ° C, which is the hot weather condition, and the lowest temperature is 25 ° C or higher during the night, Irrespective of other irrigation control conditions, the irrigation pump is operated to be irrigated through the electromagnetic valve 40 for a predetermined time. The duration of the watering can be set in the control panel.

따라서 본발명은 액비를 위한 양액을 간편하고, 편리하게 선택혼합하여 관수량을 조절하여 관수할 수 있으며 또한, 여름 열대야 때도 식물성장이 양호하여 식물의 생산성이 증가하는 현저한 효과가 있다.Therefore, the present invention has a remarkable effect that the nutrient solution for potting can be easily and conveniently mixed with water to control irrigation water, and the plant growth is good even in the summer in the summer.
